Title: Improvements in or connected with the coupling of thermionic valves
IPC: H03F1/50
Filed: 1929-03-15
Abstract: 330,956. Chambers, W. A.., and British Talking Pictures, Ltd. March 15, 1929. Thermionic valve circuits.-In method of coupling thermionic valves, the grid of a succeeding valve is directly connected to the anode of a preceding valve, consequent increase in the potential of the grid being compensated separately in the individual leads to the electrodes. Fig. 1 shows three cascade connected valves supplied from a common high tension source A. The resistance R4 is chosen so that its voltage drop provides the requisite grid bias for valve V1, while the anode resistance R1 maintains the required potential difference between anode and cathode of V1 plus the drop across R4; resistance R5 maintains the cathode of valve V2 at a potential equal to that of the anode of valve V1 plus the requisite grid bias voltages, while R2 is such as to maintain the anode of V2 at the necessary potential with respect to the cathode and so on. Thus the final anode is at maximum potential, the anodes of the preceding valves being at progressively lower potentials, while for the cathodes the reverse is the case. In a practical embodiment of the invention, Fig. 2 (not shown) valves having indirectly-heated cathodes are employed, the heaters being fed from separate low tension windings on the supply transformer. The intervalve couplings comprise a resistance for the first and second and a lowfrequency choke for the second and third valves. Specifications 127,651 and 290,032 are referred to.

Filed: 1931-03-20
Abstract: <PICT:0368998/III/1> <PICT:0368998/III/2> <PICT:0368998/III/3> For performing electrometrical volumetric analysis by means of the apparatus described in Specification 364,939, as applied to the determination of the dielectric constants of liquids and solids, the titration vessel shown in Fig. 1 of that Specification is replaced by a second condenser K2, between the plates of which the substance under investigation is placed.  The dimensions of the coils S1, S2, S3 are reduced in order to obtain a higher frequency.  These coils may be mounted on a three-coil holder and may be honeycomb coils of 300, 50, and 100 turns respectively. Fig. 2a shows a construction of the measuring-condenser K2 suitable for use with liquids.  For use with solids the form shown in Fig. 2b may be used.  This consists of a crucible in which the substance is melted, its dielectric constant being measured on solidifcation.  The measurement is effected by first setting the milliammeter MA to zero with the measuring-condenser disconnected, and then taking readings with the measuring-condenser filled successively with air, a standard test liquid such as ether, and the substance to be analysed.  From these readings the dielectric constant may be calculated by the use of a formula given in the Specification.

Filed: 1961-03-10
Abstract: 923,136. Automatic phase-control systems; radio-diversity receivers. STANDARD TELEPHONES & CABLES Ltd. March 10, 1961 [March 14, 1960], No. 8858/61. Class 40 (5). In a radio-diversity receiving system having channels liable to phase errors, each I.F. (of equal frequency) is applied to a pair of phase comparators 13, 15, one through a 90-degree phase shifter 10, with their other (reference) inputs the combined channel output, of constant amplitude, from a limiter 12. The phase comparator D.C. outputs are therefore proportional to cos # and sin # where # is the phase error of the I.F. relative to the reference combined output. The two D.C. outputs are then applied to balanced amplitude modulators 8, 9 receiving as inputs the two I.F. inputs (differing by 90 degrees in phase) to the phase comparators 13, 15 so that the combined vector output of each balanced modulator pair is rotated in phase by # relative to the initial I.F., i.e. is co-phasal with the combined reference wave from the limiter 12, and proportional in amplitude to the initial I.F. Moreover, this combined output is maintained constant in phase even if the I.F. is angle modulated due to the time constant of the low-pass filters 14, 16, preceding the modulators. The combined output may be detected by a frequency discriminator 17. The system may be applied to space, frequency, polarization or angle diversity.

Abstract: 627,638. Frequency measuring. GENERAL ELECTRIC CO., Ltd., LAMONT, H. R. L., and ROBERTSHAW, R. G. April 1, 1947, No. 8895. [Class 37] [Also in Group XL (c)] In a standing wave detector of the type comprising a short length of transmission line, e.g. rectangular section wave-guide 4 along which a pick-up connected to a detecting instrument can be moved, the middle line of the transmission line and a narrow slot in which the pick-up probe moves follow arcs of circles of radii large compared with the guide crosssection. As shown, the pick-up, which comprises a .tungsten probe 23 mounted in an adjustable plunger 36, which acts as a matching transformer, is supported by an arm 14, constructed as a rectangular section wave-guide and pivoted at 13 in ball-bearings, and is adjusted by a micrometer screw 28. The bearing-head 13 is hollow and forms with a hole in the base-plate a circular wave-guide 15 connecting the moving arm wave-guide 14 to a stationary rectangular wave-guide 16 on the base having a coupling 19 for connection to a crystal or like detector. An annular slot 35 acts as a filter choke to eliminate variations of wave-form at the junctions of the fixed and rotary-parts of the circular wave-guide. Adjustable pistons 32, 33, 34 match the impedance of adjoining sections of wave-guide. Arcuate ridges on the pick-up head project into and close the slot on either side of the probe, and arcuate slots a quarter-wave deep are cut in the head on either side of the ridges to reduce leakage radiation (Fig. 5, not shown). In an alternative arrangement (Figs. 5, 6, not shown), the pick-up is carried by two arms projecting from a bearing, and the detector is mounted on the arms for rotation with the pick-up and connected to it by a short length of wave-guide.
